Mysterious Universe launches a multi-part saga based on Warren Smith's 1970s book This Hollow Earth, exploring the claim that vast inhabited worlds exist beneath our feet. Hosts Brayden Thomas and Joe Hodgdon cover Edmund Halley's concentric-sphere theory, the Agartha legend, the sinister Deros, and the deathbed tale of Norwegian sailor Olaf Jansen, who claimed to have lived among giants inside the Earth. The episode also ties hollow Earth lore to UFOs emerging from below, secret chambers under the pyramids, Nero's hunt for subterranean treasure, and reports of underground cities and beings.
